What would you do?

Quick back story - I recently purchased a lot of 1984 Donruss commons on eBay to help fill in gaps in my set and to replace some cards that were badly off centered.

I got the cards yesterday and was amazed at how well centered they were. After putting the cards I did not previously have in the 3x3 sleeves, I started to replace some of the off centered cards. I noticed when I compared the older card I had pulled from a box 30+ years ago with the new ones I had received that the new ones seemed just a little smaller. Not much but everyone was just a little narrower.

Now I paid like $5 including shipping for this lot so I don't have a lot of money in this deal but does it seem likely that someone would trim penny commons? Is it worth my while to pursue it or do I just accept that they look fine and the difference is really small? Financially of course there is no real incentive, but my thought is if these really are trimmed then what else is this seller doing on more expensive cards?

Hmm, seems odd to trim penny cards. Could they maybe have been cut like that from the factory? You could maybe ask the seller about it. Start it by saying your're not looking to return them, or open a case, just curious. See what happens.
